Robust ferromagnetism in wafer-scale Fe₃GaTe₂ above room-temperature.

ABSTRACT: The discovery of ferromagnetism in van der Waals (vdW) materials has enriched the understanding of two-dimensional (2D) magnetic orders and opened new avenues for fundamental physics research and next generation spintronics. However, achieving ferromagnetic order at room temperature, along with strong perpendicular magnetic anisotropy, remains a significant challenge. In this work, we report wafer-scale growth of vdW ferromagnet Fe₃GaTe₂ using molecular beam epitaxy. The epitaxial Fe₃GaTe₂ films exhibit robust ferromagnetism, exemplified by high Curie temperature (T_C = 420 K) and large perpendicular magnetic anisotropy (PMA) constant K_U = 6.7 × 10⁵J/m³ at 300 K for nine-unit-cell film. Notably, the fer
